论文简介    Abstract The displacement instability of the thermally grown oxide (TGO) under thermal cycling is a fundamental source of cracking within the ceramic top-coat (TC) in a thermal barrier coating system. The effect of TGO creep on TC cracking induced by cyclic instability is numerically investigated in this work. Temperature-dependent elastic–plastic properties of each coating layer are considered in a finite element analysis. A power law is adopted to model the creep behavior of TGO and bond-coat (BC), and TGO growth at high ...
